A flexible transparent copper circuit, a preparation method therefor, and a application thereof. The preparation method specifically comprises the following steps: (1) uniformly coating a gel containing copper powder on one side of a glass sheet, and drying same to form a copper film layer; and (2) placing the one side of the glass sheet coated with the copper film layer opposite to a polymer material, scanning the other side using a laser beam such that the copper film layer is transferred to a suropposite to of the polymer material, and performing post-processing to obtain a flexible transparent copper circuit.
